5 of Massachusetts, have invented certain new and useful Improvements in Domest c Boilers, of which the following is e specifi; I

catioo, reference being hadto the accompanying ira ings.

This im'e ion relates to. new and useful improvements in domestic cooking boilers, an object, thereof is the provision of e boiler of khis class iii which several kinds 0 food my be cooked a: the some time.

r A furtbei' objek't of this invent-ion is glue provision of :1 boiler comprising a cylindrical casing formed; of two seciions tclescopi: cally connected together, and a plurality of receptacles removably (lisposecl Wit-loin the casing.

A still further object of this-invention is the provision ofe cooking boiler comprising e eylincli-ical casing composed of two see time; ielcecopically conneetefl together, 3M1

means for automatically allowing steam to cseop: en the pressure iheieof heoomes loo 11k: in the casing.

With end other objects in VlfiW, my

invention coveiisfs in certz in novel conetruel 6 (ions, combinations and arrangements of ports to be lieminafier more fully described, claimeiil and. illustrated ire the accompany in (lrowings in which-.

Referring: more particularly to Joe (iliivk logs, the numeral 1 designates generally a cylindrical casing comprising in upper ecotion .2 and a lower section 8, the upper section being reduoecl at its lower end 38 at 4 and adapted to slidingly engage in the lower: section 3, the shoulder'fi formed by the re dueed poriion of the opper'section forming a stop to limit. the movemeo'l of the upper seciioii \Jlliilln the lower section the easing. Seeied on be 6 of the io wer seelion 3 it; a supporting member comprising bars 1 enri 8, the be? i being formed inlev mediate of its ends with an upwardly open-- ing slot 9 and the bar 8 being'formed inter hog slot 10 Tllfi slels of the bars are adept letio i with the wall If the casing.

ed to be engaged to hold said bars l'ogether, and the ends of the bars are adapted to fiend to the wall of the casing so that the supporting member will be held from movemcr l .fiheiein The bars 7 and 8 are formed new their opposite ends with upstanding loge l1 and sealed upon the supporting member is a cylindrical receptacle 12 which is of substantially less diameter th:m the casing and is relM-ively of less height than the height. of the lower section 3 of the Qoeing i lie u'petzancling lugs 11. on the bars l lie eiippo 'lingmember are adapted to egg-ego the periphery of the recepiecle 12 be pieionb lele gl movement-oi the receplecle with relation (0 bhe casing and also io ma lman; :lge receptacle 12 in, spaced to Suitable handles 13 are secu 'ed to the receptacle 1;} wlie 'eby the receptacle. may be readily remiwed from the casing.

Semicylindrical receptacles 14 are suppoyted upon llic upper edge of the recepmoles (i-e a. cover fol tbe receptacle iii of t r Me llamllee 17 may be eecm-ed to the opposite sides of the recepiacles 1 for i'eiiioving the rccepocies when deb sixed, if ilesii'ooi, the reduced extension 4 of the upper. seeiionof the casing 2 may exienrl {o the bolgtom of the section 3 and the lQWQE' c-xi 'emiiy of the extension 4 may be formed Willi plurality of diametrically opposed slots 18 which are adapted @0- engage over;- {he bare T and 8 of the supporting membesa To provide for the escape of steam from the casing, an opening 19 is formed in the central portion of the cover :20 of the casing, and this opening 19 mo y be also need to replenish llie mpply of water in the boiler and in ll!" cmmcciion I provide a trans? versel v. extending channel iron 21 which is secured to flip lower face of the cover 20, ilie opposite ls of the channel icon e);- iem'ling to p1, ite adjacent the wall 0 the casing whereby the water may flow to the bottom of the casing between the inner pcriphcry thereof and the outer peripheries of the rct'eptzudes supported within the casing. If desired, handles 22 may be secured to the upper and lower sections of the casing whereby the sections 'may be carried separately or the entire casing may be carried by the handles it? on the lower-section thereof.

The operation of my device is as follows:ln the practical u e of my invention, food is placed in the receptacle l2 and 14-, \vlnzrcupen the receptacle 12 is disposed on the bars 7 and S inwmdtv ot the lugs 11 thereon so that. the receptacle is spaced from the wall of the casing. and the receptacles 14 mounted on the receptacle. 1? with the grooves 15 in engagement with the upper edge of the receptacle 1) whereby the receptacles 1-1 are also held in spaced relation with the casing. \Vater may be then poured in the lower section 3 of the boiler, the receptaele 12 being maintained above the water by the supporting bars 7 and S. The reduced end 4 of the upper section will then be telescopically mounted within the lower section 3 of the casing and the boiler is then ready for use. it is apparent that the steam generated from the water in the casing will com; the food contained within the several receptacles and should the pressure of the steam within the casing become too grat, the upper section 2 will be Iorccd upwardly by reason of the pressure, so that steam may escape through the openings 23 formed in the reduced portion of the upper section of the casin It will be seen that when the pressure has been relieved within the casing, the upper section 2 will again move downwardly within the lower section 3 until the pressure within the casing again becomes too great.

It will be seen from the above description taken in connection with the accompanving drawings that; I have provided a cooking boiler in which several varieties of foods may be cooked at the same time, the boiler being formed of a minimum number of parts whereby it may be cheaply manufactured.

\Vhile the construction illustrated in the accompanying drawings gives the preferred embodiment of my invention, it will be understood that minor changes in construction may be made without departing from the spirit of my invention or sacrificing any of its advantages as determined by the scope of the appended claims.

I'Iaving thus described my. invention, what I desire to claim and secure by Letters Patent is v 1. A boiler comprising a casing, a cylin- 'drical receptacle disposed within said casmg, a pair of semi-cylindrical receptacles, each of mar semicylindrical receptacles having a groove formed in its curved face at its lower extremity, the grooves in said receptacles being adapted for engagement with the upper edge of the first mentioned receptacle, as and for the purpose described.

2. A boiler of the character described comprising a sectional casing, a supporting member disposed within said casing, a cylindrical receptacle mounted on said supporting member, semi-cylindrical receptacles having arcuate grooves therein disposed upon the iist mentioned receptacle, the grooves in the semi-cylindrical receptacles being adapted for engagement with the upper edge of the first mentioned receptacle, as and for the purpose described.

3. A. boiler comprising a casing, a cylindrical receptacle disposed within said casing. semi-cylindrical receptacles mounted on the first mentioned receptacle, each of said semi-c vlindrical receptacles having a groove formed in its curved face at its lower extremity, said grooves being adapted for engagement with the upper edge of the first mentioned receptacle, Said semi-cylindrical receptacles when in engagement with the tially the same diameter as'said first mentioned receptacle, whereby relative movement of the several receptacles is prevented.

4. in a device of the character described, a Easing comprising an upper and a lower in; in spaced relation with the wall thereof, the upper section having a central opening formed therein, and a channel member extending transversely of the upper section and disposed below the opening therein, the opposite ends of said channel member terminating in vertical alinement with the space between the periphery of the receppurpose described.

5. In a device of the character described, a casing comprising an upper and a lower receptacle disposed in the lower section in Qspaccd relation with the wall thereof, the

first mentioned receptacle being of substan-.

section. a receptacle disposed in said 08.8

section telescopically connected together, a

tacle and wall of the casing, as and for the
